WAGON-BRAKE.

$PECIFIOATION' forming part of Letters Patent No. 731,117, dated June16, 1903. Application filed August 22,1902. Serial No. 120,660. NomodeldTo all whom it may concern.-

Be it known that I, CYRUS MILTON MCCOY, a citizen of the United States,residing at Stanhope, in the county of Hamilton and- State of Iowa, haveinvented a new and use-' ful Vagon-Bra'ke, of which the following is aspecification.

The invention relates to improvements in wagon-brakes.

The object of the present invention is to improve the construction ofwagon-brakes and to increase the strength, durability, and efliciency ofthe same and to provide a simple and comparatively inexpensiveconstruction adapted to be applied to the running-gear or to the body orbox ofa wagon and capable when applied to the running-gear of enablingthe body or box to be readily detached when it is desired to use therunning-gear for other purposes.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side eleva tion of a wagon-brakeconstructed in accord- .ance with this invention and shown applied to awagon, the brake-shaft being mounted. on the running-gear. Fig. 2 is aplan view of the same, the wagon body or box being removed. Fig. 3 is atransverse sectional View of the same, illustrating the manner ofmounting the brake-shaft.

Fig. 8 is a side elevationillustrating the manner of mounting the brake-shaft. Fig. 9 is atransverse sectional view of the same. Fig. 10 is a detail sectionalview illustrating the construction for detachably secur ing theconnecting rod or bar to the arm of the brake-shaft. Fig. 11 is asimilar view Fig. 7 is a detail illustrating the manner of securing thesections of the connecting bar or rod together.

Like numerals of referencedesignate correspondingparts in all thefigures of the drawings.

1 designates a transverse brake-shaft designed to be constructedofeither tubular or solid metal and provided-at its ends with dependingarms 2, which may be formed by bending the ends of the shaft downward,as clearly illustrated in Fig. 3; but the depending arms 2, which carrybrake-shoes 3, may consist of separate pieces coupled to the bodyportion of the shaft, if desired. The brakeshaft is journaled inbearing-eyes 4 of bolts which extend through a transverse bar or beam 5and which also form fastening devices for securing a bowed brace 6 tothe bar 5, as clearly shown in Fig. 3. The transverse bar 5'is securedby bolts 7 or other suitable fastening devices which pass through thefront portions of the rear bounds and through the bowed brace 6, whichforms a truss for supporting the brake mechanism. The brakeshaft is heldagainstlongitudinal movement by means of keys 8 and washers 9, the keysbeing passed through the shaft and the washers 9 being interposedbetweenthe keys and the bearing-eyes. The brakeshoes are mounted invertically-adjustable clamps 10, having recesses to receive thebrake-shoes and pro-' Vided-with eyes for the reception of the arms 2.The clamps, which are secured at the desired adjustment on'the arms 2 bymeans of setscrews 11, are providedat opposite sides of thebrake-shoe-receiving recesses with perforations for the reception ofbolts 12. this construction the brake -shoes may be readily adjusted toenable them to eifectively engage the wheels 13.

The brake-shaft is held against movement longitudinally of therunning-gear by means of bracing -rods 14, provided at their front endswith eyes to receive the brake-shaft and extending rearward therefromto'the rear bolster and provided at their rear ends withinwardlyextending engaging portions 15. The inwardly-extending engagingportions 15 project through eyes 16 and are secured to the same by meansof keys 17 and washers 18. The eyes are provided with threaded shanks toform eyebolts which pass through the rear bolster. 1

The brake-shaft is detaohably connected with the wagon body or box 19 byseparable hangers composed of two bars or members 20, pivoted at theirupper ends by bolts 21 or other suitable fastening devices to the sidesof the, wagon body or box and depending therefrom to the brake-shaft andprovided at their lower ends with recesses 22, extending inward fromtheir inner edges and forming an eye to receive the brake-shaft when thebars or members 20 are closed. The bars or members are secured in theirclosed position by means of a bolt 23, located beneath the wagon body orbox and passing through perforations 24 of the bars or members. The bol23 is adapted to be readily removed to permit the bars or members to beswung apart, as illustrated in Fig. 4, for releasing the transversebrakeshaft to permit the removal of the wagon body or box. The hangersor connecting devices assistin holding the wagon body or box in positionand at the same time operate to support the brake mechanism and therunninggear.

The brake-shaft is provided at one end with a rigid upwardly-extendingarm 25, which is connected bya rod or bar 26 to the lower end of anoperating-lever 27, and the said connecting rod or bar 26 is composed offront and rear sections or members, the rear section or member 46 beingprovided at its front end with a cuff 47, receiving the rear end of thefront section. The adjacent ends of the sections or members are providedwith perforations for the reception of a fastening device 48, wherebythe connecting rod or bar is adapted to be varied in length to regulatethe movement of the brake shoes. The rear section is provided at itsrear end with a spring-actuated catch 49, and it has a plate 50interposed between the engaging end of the catch and the rear end of thesection 46 and secured to'the latter. The plate 50 is angularly bent,and its outer portion is spaced from the rear end of the section ormember 46 to receive the arm 25 of the rockshaft. The catch is providedbetween its ends with perforated ears for the reception of a pivot 51,which also passes through similar ears 52 of the section or member 46. Acoiled spring 53 is disposed on the pivot and is adapted to hold thecatch in engagement with the arm 25 of the rock-shaft. The catch isprovided at its engaging end with a lug or projection 54, which extendsthrough an opening of the plate 50 and engages an aperture of the arm25, whereby the said arm 25 is secured to the connecting device. Thefront or inner end of the catch is adapted to be depressed to throwtheengaging end outward from the arm 25 to separate the parts when it isdesired to remove the wagon body or bed.

The brake-lever is fulcrumed between its ends on a bolt 28 to enable itsupper or handle portion to be drawn backward in applying the brake,thereby rendering the operation of the brake more convenient for thedriver than those brakes which are applied by throwing the upper portionof the brakelever forward. The said lever 27 is fulcrumed within asupporting-frame consisting of a central longitudinal oblong portion 29and approximately L-shaped arms 30, having upright portions forattachment to the wagonbody and provided with horizontal portions whichare angularly bent for offsetting the central oblong body portion fromthe wagonbody. The outer side of the central portion 29 of thesupporting frame or bracket is provided with an. upwardly-extendingtoothed segment 31, forming a ratchet and adapted to be engaged by aspring-actuated pawl or detent 32 of the operatingdever. Thespringactuated dog, which is located above the ratchet, passes through acasing or housing 33, in which the coiled spring 34 is arranged andwhich is provided with a depending arm or lug 35, located at the outerface of the toothed segment. The toothed segment may be provided withbeveled teeth, as shown in Fig. 1, to permit the dog or detent to slideforward freely over the segment; but the teeth of the segment may beprovided at each of their faces with a shoulder, as illustrated in Fig.7. The spring-actuated pawl is connected by a rod 36 with avertically-movable handle 37, having an inner portion or shank 38, whichis slidably mounted in a slot 39 of the upper portion of the lover. Theshank 38 may be secured in the slot in any desired manner, and thehandle 37 is located beneath'a handle or grip 40, formed by bending theupper end of the operating-lever outward. The two handles 37 and 40 areadapted to be simultaneously grasped for enabling the operating-leverand the spring-actuated pawl to be simultaneously operated. The pawl islocked out of engagement with the toothed segment by means of a pivotedheart-shaped plate 41, having a recess at its free end and adapted to beswung upward longitudinally of the operating-lever to support themovable handle 37 in an elevated position.

In Figs. 8 and 9 is illustrated a modification of the invention, inwhich the brakeshaft 42 is mounted on the body or box 43 in suitablebearings 44, which aresecured to the side steps 45, but which may bemounted in any other desired manner. The brakeshaft, which is providedwith brake-shoes similar to those heretofore described, is connected bya rod with a brake-lever constructed and arranged similar to thatheretofore described.
